Question

Which point is on the graph of f(x)=4^x?
A.(0,0)
B.(1,4)
C.(4,1)
D.(0,4)

Answer 1

B

Explanation:

to determine if the coordinate point is on the graph, substitute the x-coordinate into f(x) and if the value corresponds with the y-coordinate then the point is on the graph.

f(0) =
`4^(0)` = 1 → (0, 0) is not on graph

f(1) =
`4^(1)` = 4 → (1, 4 ) is on graph

f(4) =
`4^(4)` = 256 → (4, 1 ) is not on graph

f(0) =
`4^(0)` = 1 → (0, 4 ) is not on graph
